  • The following Maintenance Procedures should only be maintained by qualified service personnel.

  • Chiller Maintenance

  • DANGER!

  • Use approved Lock Out/Tag Out procedures to disconnect power from the unit. Wait 20 minutes after disconnecting power from the unit before opening any compressor access covers. The DC link capacitors store enough energy to cause electrocution.

  • Electrical System

  • Maintenance of the electrical system involves the general requirement of keeping connections clean and tight. Pump interlocks and flow switches should be checked to be sure they interrupt the control circuit when tripped.

  • Cleaning and Preserving

  • A common cause of service calls and equipment malfunction is dirt. This can be prevented with normal maintenance.

  • The system components most subject to dirt are:

  • Water Treatment

  • Special care must be taken when utilizing open system water that is usually not treated (such as lakes, rivers, and ponds). The use of untreated water will result in corrosion, erosion, slime buildup, scaling, or algae formation. Water treatment service must be used. Special tube and water head material may be required to reduce damage from corrosion. Daikin Applied is not responsible for damage or faulty operation from untreated or improperly treated water. See “Water Piping” on page 17 for caution stateme
